Behold the Procrastertron!

[lord preset]

I just finished an amp I am calling the Procrastertron in honor of it sitting on the bench since January. It began as a Tweed Bluezmeister as documented in: https://tubeamparchive.com/viewtopic.ph ... sc&start=0

I completed the initial build fairly quickly, ran into some slow going troubleshooting my mistakes and got sidetracked on to other projects. It's baleful stare finally made me feel guilty so I recently went back to finding what I did wrong. Lots of things as it turns out. For one thing 150R resistors look an awful lot like 150K resistors if you aren't paying enough attention. Initially I was getting way early breakup and unresponsive tone controls on the clean channel and not much at all on OD. I bypassed the Clean/OD switching and concentrated on getting the clean channel working. In the process of fiddling I finally ended up ripping out the rock/jazz switch and reverting to a fender BF tonestack with some altered cap values. I was still not happy with the headroom and I ended up switching from cathode bias to fixed bias.

When I turned to the OD side I discovered I had a 150R (vs 150K) resistor on the plate of V2B, as well as some switch routing errors. I also ended up taking out the "Trim Boost" pot and relay as they didn't seem all that useful to me.

So now I have a nice. light compact amp with good cleans and OD but it no longer bears much resemblance to the Tweed Bluezmeister design I started with. I'm sure that if I had been more patient debugging the original build instead of ripping stuff out it would have been great but this also works for me. And what started as a relatively neat build for me ended up looking quite a bit more disheveled after lots of rework,

Looks great! Glad you got it finished. Are you using an 12AY7 in V1?

Nope, just a 12ax7.
